Compressed view for List of Users column when displaying multiple entries (3+)

We have a nice displayer if the column holds a List of Users property, but the problem is that we don't handle well multiple entries (>3) when 'Multiple Select' is enabled.

A. We could limit the displayer to list just the first 3-5 entries;
B. We could change the displayer and list just avatars, instead of giving also the name and id;
C. Maybe use the 'size' param (although is suppose to do something else, but is completely useless) and specify how many entries we want to display.
